CPAP battery solar charging question

[Mr_Biggles]

I purchased a Pilot 12 Plus battery to use with my CPAP machine while off grid. I’m thinking of getting a Colman 55W solar kit to top up the battery while on 2/3 night camping trips. I don’t know much about solar kits. Would this kit be large enough for the battery ?

I did a bit of reading about this battery and it appears it has to be charged from its own 120v charger. If that's the case, you may find it difficult to connect the output of a solar controller to it.

It may require you to have an inverter/batteries already on board. 100w is just barely enough.

No problem. You can make a nice passover humidifier from a Tupperware container and some old air delivery hose ends, glued to the lid (at opposite ends). I need humidification always and a passive humidifier was the only way to go.

Used to be CPAP supply places sold passive units but they don't anymore, for what reason, I haven't a clue.

Don't use your humidifier, that will suck the pack dry in jig time. I use a pass over humidifier I made from a Tupperware container. I recharge my pack(s) with my Zamp 150 watt solar. Don't think 55 watt is enough.

I run a pair of Li-Iron packs. I can get 3 days from 2, no problem,
